support of the ICU custom rules

[tomatolog]

Proposal:

it could be better to add support of the custom rules into ICU integration

• Rule Based Number Format
• Break Rules
• Collation Rule

it could be better to add support of these or some of these options for morphology='icu_chinese' and prohibit all use of the exceptions \ wordforms \ stopwords for morphology='icu_chinese' or ngram_chars.

As cjk tokenization is related on content and exceptions \ wordforms \ stopwords \ morphology got applied at the different stages on the token processing pipeline and general content got lost there.

the related issue https://github.com/manticoresoftware/manticoresearch/issues/2507 there exceptions can not work with the morphology='icu_chinese'

or maybe upcoming Jieba integration from the https://github.com/manticoresoftware/manticoresearch/issues/931 could handle such cases
